HYDRAULIC KIT

 

 

 
 

 

 

• For the connection of the hydraulic kit with the 

closed circuit (collectors, tube heat exchanger 
which  is  located  at  the  bottom  part  of  the 
boiler)  refer  to  the  hydraulic  diagram  of  the 
solar system on page 19. 

• The connection of the expansion vessel with 

the safety valve of the hydraulic kit must have 
greatest  length  of  2  meters,  without  any 
corners  and  without  any  high  air  gathering 
area. The diameter is 

3/4”. 

• After  the  plumbing  installation,  the  closed 

circuit  must  be  cleaned.  The  cleaning  of  the 
system is achieved with water for 15 minutes 
by isolating the circulator from 

it’s two valves 

which  are  located  before  and  after  it  and  by 
opening the two inlets / outlets of the system. 
The  inlets  /  outlets  have  records  (male)  for 
connection to a plastic pipe. 

• Before the filling of the closed circuit, we must 

check  the  water  tightness  of  all  of  the 
connections.  We  can,  for  instance,  during 
the  cleaning,  turn-off  one  of  the  emptying-
filling  valves and  use  a  pressure  pump  or 
the  pressure of  the  water  supply  so  that  we 
can  raise  the  pressure  to  5  bars  for  15 
minutes. 

Attention: 

the  expansion  vessel  must  be 

isolated so as to minimize the overload of the 
maximum functioning pressure. 

• The  mixing  of  the  antifreeze  liquid  must  be 

done  before  the  filling  and  in  accordance  to 
the  lowest  environmental  temperature  (see 
table on page 23). 

• The  filling  of  the  system  can  be  done  either 

from  the  top  part  of  the  collector,  by  the 
gravity or with a pump from the hydraulic kit. 
The functioning pressure, between 1,5 and 3 
bar,  can  be  achieved  with  the  pressure 
pump  or the  pressure  of  the  water  supply. 
We  constantly  check  all  of  the  points  of 
degassing,  while  filling  simultaneously  with 
liquid. 

• All of the installations and connections of the 

system  must  be  done  according  to  the 
electric,  plumbing,  and  construction 

etc… 

regulations applicable in your country. 

• It is recommended that a pail is placed under 

the hydraulic kit in which water or liquid will be 
accumulated  from  the  dripping  of  the  safety 
valve.  This  is  really  useful  during  the  filling 
and  degassing  or  the  hydraulic  testing  since 
the valve opens at 6 bar. 

 
 

 

 

• All of the piping that leave and return from and 

to the collectors have to be properly insulated 
so that they can withstand temperatures from 
-30ºC  up  to  +120ºC.  It  is  also  necessary  to 
use  an  anti-UV  (solar  radiation)  for  the 
insulation. 

• The insulation must have suitable thickness in 

Accordance to the local climatic conditions. 

• The distance between the collectors and the 

tube heat exchanger of the boiler must be the 
least  possible  so  as  to  minimize  the  thermal 
losses. 

• Air trapping areas must be avoided.  If this is 

not possible, an automatic degasser must be 
installed at that point. 

• The   diameter   of   the   pipes  must   be  from 

∆18mm  -  22mm  for  distance  up  to  20m  and 
∆15mm for distance down to 12m. 

• All  of  the  connection  records  which  will  be 

used  must  withstand  pressure  of  6  bar  and 
temperatures between 

–30ºC and + 200ºC. 

• After  the  guarantee  has  expired,  it  is 

recommended  that  a  yearly  check  is  made 
on  the installation and the connections.
